Every day at the National Breath Center, Dr. Miller listens as patients relate personal horror stories of the effects of bad breath — lost promotions because of chronic halitosis, offending co-workers, or lost sales because of offensive breath odors. People who have tried every treatment come to the National Breath Center for a lasting cure that removes the direct cause of bad breath. Dr. Miller believes that if chronic bad breath is ruining your life, you deserve to be freed of this condition. The National Breath Center offers a money-back guarantee on its Total Cure professional treatment.
